Hitler loved dogs and children. He also slaughtered millions of them.
I didn't know your uncle personally, but I know he was a MAGA who was so dug in that he literally put his obsession for Trump ahead of his love for his family, and died for it, abandoning his 4 kids. Anyone who puts their politics or religion ahead of their love for their own children is a sociopathic loser.
What else do I need to know about him? Nothing he possibly did is going to redeem him for being an unapologetic MAGA sociopath to the very end.
